摘要: Abstract Samples of mordenites with variable Si/Al atomic ratio and different counter-ions were exchanged copper ions by two methods – the conventional treatment in water solution microwave-assisted procedure. The zeolite-solution concentration kept equal for both procedures. We report on results XRD, TGA XPS studies. analysis confirms that despite observed differences spectra samples are the +2 oxidation state. preparation method influences content surrounding, but does not change electronic state ions.
